Description

Technical Field

[0001] The present application relates to the technical field of gate barriers, and in particular to a telescopic gate barrier. Background Art

[0002] As a common space divider, telescopic gates are mainly used in residential interiors or courtyard landscapes. The device achieves physical partitioning through a retractable structure, and can quickly divide temporary activity areas according to usage needs. In indoor scenes, its flexible characteristics support dynamic segmentation of living rooms, corridors and other spaces; in outdoor courtyard environments, it can effectively plan courtyard partitions with different functions.

[0003] In the related art, the telescopic gate includes a fixed seat, a rotating drum and a partition cloth. Two fixed seats are provided, and the two fixed seats are respectively located at the two ends of the rotating drum, and the rotating drum and the fixed seat are rotatably connected. One end of the partition cloth is fixed to the rotating drum, and the partition cloth is wound around the rotating drum. A torsion spring is provided in the rotating drum. When the free end of the partition cloth is pulled by hand, the rotating drum rotates, thereby driving the torsion spring to rotate. The torsion spring forms a rotational restoring force. When the free end of the partition cloth is pulled a certain distance and fixed, the partition cloth will be in a taut state under the action of the rotational restoring force of the torsion spring. When the free end of the partition cloth is loosened, the rotating drum rotates in the opposite direction under the action of the rotational restoring force of the torsion spring, thereby realizing the automatic winding of the partition cloth.

[0004] However, since the tension of the partition cloth is formed by the rotational restoring force of the torsion spring, the partition cloth must be pulled a certain distance before it can be in a tensioned state. However, for some occasions with a small partition distance, the distance the partition cloth is pulled is small, and the rotational restoring force of the torsion spring is small, which makes it difficult for the partition cloth to be in a tensioned state, affecting the user experience. Summary of the invention

[0005] In order to enable the partition cloth to be tightened even when the pulling distance is small, the present application provides a telescopic gate.

[0006] The telescopic gate provided in this application adopts the following technical solution:

[0007] A telescopic gate fence comprises a first fixed seat and a second fixed seat, which are arranged at an interval; a rotating drum, whose two ends are rotatably connected to the first fixed seat and the second fixed seat respectively; a partition cloth, one end of which is fixed to the rotating drum, and the partition cloth is wound around the rotating drum; a torsion spring, which is passed through the rotating drum, one end of which is fixed to the rotating drum, and the other end is connected to the first fixed seat; a torsion piece, which is connected to one end of the torsion spring close to the first fixed seat, extends out of the first fixed seat, and is used to torsion the torsion spring; a locking assembly, which is connected to the first fixed seat and is used to lock the torsion position of the torsion piece.

[0008] By adopting the above technical solution, when the user needs to use the retractable door barrier, fix the first fixed seat and the second fixed seat at the position where they are needed, then pull the free end of the partition cloth to the required position and fix the free end of the partition cloth, thus completing the partitioning. At this time, the user feels whether the partition cloth has reached the taut state. If the partition cloth has not reached the taut state, the user first releases the locking component so that the torsion member can twist the torsion spring, and then twists the torsion spring in the direction of tightening the torsion spring, that is, twists the spring in the direction of increasing the rotational restoring force of the torsion spring, so that the rotational restoring force of the torsion spring increases, making the partition cloth taut, so that the partition cloth can also be taut when the pulling distance is small.

[0009] In addition, when the user pulls the partition cloth a long distance, the rotational restoring force of the torsion spring will become relatively large, which is relatively laborious for some users, such as children and the elderly. For this situation, the locking component can be released first so that the torsion member can twist the torsion spring, and then the torsion spring can be twisted in the direction of loosening the torsion spring to reduce the initial force of the torsion spring, thereby reducing the burden of pulling the partition cloth later.

[0010] In some embodiments, the locking component includes: a locking plate fixed to the first fixed seat, and one end of the torsion member extends out of the locking plate; a tension member connected to the extending end of the torsion member for pulling the torsion member so that the other end of the torsion member abuts against the locking plate; the torsion member is slidably connected to the torsion spring, and the sliding direction is along the axis direction of the torsion spring.

[0011] By adopting the above technical solution, when the user uses the locking component to lock the torsion member, use the tension member to tighten the torsion member, the torsion member abuts against the locking plate, and a large frictional force is formed between the torsion member and the locking plate, thereby hindering the relative rotation between the torsion member and the locking plate, and the position of the torsion member is locked, and the rotation position of the torsion spring is locked. Since the tension member needs to exert a certain pulling force on the torsion member, the slidable connection between the torsion member and the torsion spring can prevent the torsion member from simultaneously pulling the torsion spring, thus not affecting the use of the torsion spring.

[0012] In some embodiments, locking holes are formed at the positions of the locking plate and the torsion member that face each other. The locking holes are tapered, and the diameter of the locking holes gradually increases from the extending end of the torsion member to the other end of the torsion member. The side wall of the torsion member that faces the locking holes is tapered and is adapted to the side wall of the locking holes.

[0013] By adopting the above technical solution, when the user locks the torsion member, the tension member is used to pull the torsion member, and the tapered side wall of the torsion member and the tapered side wall of the locking hole are fitted together. As the tension member gradually pulls the torsion member, the side wall of the torsion member gradually presses against the side wall of the locking hole, and the friction between the torsion member and the locking plate gradually increases, thereby hindering the rotation of the torsion member. Since the locking hole and the torsion member fit together through the tapered surface, the friction surface is larger, making the locking of the torsion member more secure. In addition to the above, since the locking hole and the torsion member fit together through the tapered surface, the tapered surface is a rotary curved surface, and the torsion member can be locked at any position, and the stepless adjustment of the torsion restoring force of the torsion spring can be achieved.

[0014] In some embodiments, the torsion member is provided with an anti-rotation hole, the end of the torsion spring extends into the anti-rotation hole, the torsion member is slidably mounted on the end of the torsion spring through the anti-rotation hole, and prevents relative rotation between the torsion member and the torsion spring.

[0015] By adopting the above technical solution, when the torsion piece and the torsion spring are assembled together, it is only necessary to extend the end of the torsion spring into the anti-rotation hole to achieve a sliding connection between the torsion piece and the torsion spring and prevent the torsion piece and the torsion spring from rotating relative to each other, making the assembly between the torsion piece and the torsion spring more convenient and quick.

[0016] In some embodiments, the tensioning member includes a rotating ring, the rotating ring is threadedly connected to the protruding end of the torsion member, and the rotating ring and the locking plate are detachably abutted.

[0017] By adopting the above technical solution, when the user uses the tensioning member to pull the torsion member, the rotating ring is rotated, and the rotating ring first contacts the locking plate, and then as the rotating ring continues to rotate, under the action of the thread, the extended end of the torsion member continues to extend out of the rotating ring, and the abutment force between the torsion member and the locking plate gradually increases until the rotating ring can no longer rotate and the torsion member is locked. Since the thread has a self-locking effect, the relative rotation between the rotating ring and the torsion member can be stably locked, and the torsion member can be stably locked.

[0018] In some embodiments, a twist handle is fixed to the protruding end of the twisting member, and the twist handle is used to twist the twisting member; the rotating ring is fixedly connected to a toggle handle, and the toggle handle is used to toggle the rotating ring to rotate.

[0019] By adopting the above technical solution, when the user needs to twist the torsion piece, he first loosens the rotating ring by turning the handle, and then turns the torsion piece by the handle to adjust the strength of the torsion spring. After the adjustment is completed, he turns the rotating ring in the opposite direction by turning the handle to lock the torsion piece. By cooperating with the toggle handle and the handle, the user can conveniently adjust the strength of the torsion spring.

[0020] In some embodiments, the first fixing seat is hollow, and the locking plate is fixed to the open end of the first fixing seat.

[0021] By adopting the above technical solution, the part where the torsion member and the torsion spring cooperate can be hidden inside the first fixing seat, which is beneficial to the unity of the appearance. Moreover, the entire circumference of the locking plate is supported by the first fixing seat, and the connection between the locking plate and the first fixing seat is relatively stable, and the end of the torsion spring can be stably connected, so that the partition cloth can be pulled out and retracted relatively stably.

[0022] In some embodiments, an installation plate is provided at one end of the first fixing seat away from the torsion member. An end installation member is fixed to the end of the rotating cylinder, and the end installation member is embedded in the installation plate and rotatably connected to the installation plate; the installation plate is connected with a rotating locking member, and the locking member is used to lock the rotation of the end installation member.

[0023] By adopting the above technical solution, when the partition cloth is pulled out to partition the space, the locking member can lock the rotating cylinder to prevent the partition cloth from being continuously pulled, ensuring that the partition cloth can effectively partition the space. Moreover, the torsion member and the locking member are respectively arranged at both ends of the first fixing seat. The operating distances of the torsion member and the locking member are relatively close, but they do not interfere with each other, which is convenient for the user to adjust the force of the torsion spring and also convenient for the user to lock the rotating cylinder.

[0024] In some embodiments, the installation plate is provided with an axially through hole and a receiving hole that communicate with each other. The axially through hole and the receiving hole are along the axis direction of the torsion spring; the end installation member includes a sleeve and an end plate that are fixedly connected to each other. The diameter of the end plate is larger than the diameter of the sleeve. The sleeve is sleeved on the rotating cylinder, and the end plate is located in the receiving hole, and the locking member locks the rotation of the end plate.

[0025] By adopting the above technical solution, the cooperation between the axially through hole and the sleeve can realize the rotational cooperation between the rotating cylinder and the first fixing seat. The locking of the end plate by the locking member can realize the locking of the rotation of the sleeve, and further lock the rotating cylinder, so as to realize the two-way locking of the rotating cylinder.

[0026] In some embodiments, the rotating locking member includes a pressing ring. The pressing ring extends into the receiving hole, and the pressing ring is threadedly connected to the installation plate for pressing the end plate.

[0027] By adopting the above technical solution, by rotating the pressing ring, the pressing ring gradually presses the end plate. After the end plate is pressed, the locking of the end plate is realized, that is, the locking of the rotating cylinder is realized. Under the action of screw self-locking, reliable locking of the rotating cylinder can be realized.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. When the user needs to use the retractable door barrier, fix the first fixed seat and the second fixed seat at the position where they are needed, then pull the free end of the partition cloth to the required position and fix the free end of the partition cloth, thus completing the partitioning. At this time, the user feels whether the partition cloth has reached the taut state. If the partition cloth has not reached the taut state, the user first releases the locking component so that the torsion member can twist the torsion spring, and then twists the torsion spring in the direction of tightening the torsion spring, that is, twists the spring in the direction of increasing the rotational restoring force of the torsion spring, so that the rotational restoring force of the torsion spring increases, making the partition cloth taut, so that the partition cloth can be taut even when the pulling distance is small;

[0030] 2. When the user locks the torsion member, use the tensioning member to pull the torsion member. The tapered side wall of the torsion member fits with the tapered side wall of the locking hole. As the tensioning member gradually pulls the torsion member, the side wall of the torsion member gradually abuts against the side wall of the locking hole, and the frictional force between the torsion member and the locking plate gradually increases, thus preventing the torsion member from rotating. Since the locking hole and the torsion member are in contact through a tapered surface, the friction surface is large, making the locking of the torsion member relatively reliable. In addition to the above, since the locking hole and the torsion member are in contact through a tapered surface, and the tapered surface is a revolving curved surface, the torsion member can be locked at any position of rotation, and stepless adjustment of the torsional restoring force of the torsion spring can be realized;

[0031] 3. When the partition cloth is pulled out to partition the space, the locking member can lock the rotating cylinder to prevent the partition cloth from being pulled further, ensuring that the partition cloth can effectively partition the space. Moreover, the torsion member and the locking member are respectively arranged at both ends of the first fixed seat. The operating distances of the torsion member and the locking member are relatively close, but they do not interfere with each other, which is convenient for the user to adjust the strength of the torsion spring and is also convenient for the user to lock the rotating cylinder.

[0041] Next, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] The following will further describe the present application in detail Figures 1-6 with reference to the attached drawings.

[0043] Referring to Figures 1-2 , an embodiment of a telescopic door barrier disclosed in the present application includes a first fixing seat 1, a second fixing seat 2, a rotating cylinder 3, a partition cloth 4, a torsion spring 5, a torsion member 6 and a locking assembly 7. The first fixing seat 1 and the second fixing seat 2 are arranged at intervals, and both ends of the rotating cylinder 3 are respectively rotatably connected to the first fixing seat 1 and the second fixing seat 2. One end of the partition cloth 4 is fixed to the rotating cylinder 3, and the partition cloth 4 is wound around the rotating cylinder 3. The other end of the partition cloth 4 is a free end for pulling. The torsion spring 5 is inserted into the rotating cylinder 3, one end is fixed to the rotating cylinder 3, and the other end is connected to the first fixing seat 1. The torsion member 6 is connected to one end of the torsion spring 5 close to the first fixing seat 1, and the torsion member 6 extends out of the first fixing seat 1 for twisting the torsion spring 5. The locking assembly 7 is connected to the first fixing seat 1 for locking the twisting position of the torsion member 6.

[0044] When the user needs to use the retractable door barrier, fix the first fixing seat 1 and the second fixing seat 2 at the position where they are needed, then pull the free end of the partition cloth 4 to the required position and fix the free end of the partition cloth 4, thus completing the partitioning. At this time, the user feels whether the partition cloth 4 has reached the taut state. If the partition cloth 4 has not reached the taut state, the user first releases the locking component 7 so that the torsion member 6 can twist the torsion spring 5, and then twists the torsion spring 5 in the direction of tightening the torsion spring 5, that is, twists the spring in the direction of increasing the rotational restoring force of the torsion spring 5, so that the rotational restoring force of the torsion spring 5 increases, making the partition cloth 4 taut, so that the partition cloth 4 can also be taut when the pulling distance is small.

[0045] In addition to the above operation method, the user can also twist the torsion spring 5 through the torsion member 6 before pulling the partition cloth 4 to make the force of the torsion spring 5 larger, which can also enhance the taut effect of the partition cloth 4.

[0046] In addition, when the user pulls the partition cloth 4 a long distance, the rotational restoring force of the torsion spring 5 will become larger, which is more laborious for some users, such as children and the elderly. For this situation, the locking component 7 can be released first so that the torsion member 6 can twist the torsion spring 5, and then twist the torsion spring 5 in the direction of loosening the torsion spring 5 to reduce the initial force of the torsion spring 5, thereby reducing the burden of pulling the partition cloth 4 later.

[0047] In the embodiment of the present application, the first fixing seat 1 and the second fixing seat 2 are equivalent, and the torsion member 6 and the locking component 7 can also be arranged on the second fixing seat 2. Usually, the first fixing seat 1 and the second fixing seat 2 are arranged at intervals in the vertical direction. As Figure 1 shown, the first fixing seat 1 is the upper fixing seat and the second fixing seat 2 is the lower fixing seat. In other embodiments, the first fixing seat 1 can also be the lower fixing seat and the second fixing seat 2 can be the upper fixing seat. For the convenience of operation, the torsion member 6 and the locking component 7 are usually arranged on the upper fixing seat. However, for some scenarios, such as when the first fixing seat 1 and the second fixing seat 2 are suspended at a relatively high position, the first fixing seat 1 is used to represent the lower fixing seat for the convenience of the user to operate the retractable door barrier.

[0048] Refer to Figures 1-3 As shown, the locking component 7 includes a locking plate 71 and a tensioning member 72. The locking plate 71 is fixed to the first fixing seat 1, and one end of the torsion member 6 extends out of the locking plate 71. The tensioning member 72 is connected to the extending end of the torsion member 6 and is used to pull the torsion member 6 so that the other end of the torsion member 6 abuts against the locking plate 71. The torsion member 6 is slidably connected to the torsion spring 5, and the sliding direction is along the axis direction of the torsion spring 5.

[0049] When the user locks the torsion member 6 using the locking assembly 7, the tension member 72 is used to tension the torsion member 6. The torsion member 6 abuts against the locking plate 71, and a large frictional force is formed between the torsion member 6 and the locking plate 71, thereby hindering the relative rotation between the torsion member 6 and the locking plate 71. The position of the torsion member 6 is locked, and the rotational position of the torsion spring 5 is locked. Since the tension member 72 needs to exert a certain pulling force on the torsion member 6, the sliding connection between the torsion member 6 and the torsion spring 5 can prevent the torsion member 6 from simultaneously pulling the torsion spring 5, thus not affecting the use of the torsion spring 5.

[0050] Referring to Figures 1-3 , a locking hole 711 is provided at the relative position between the locking plate 71 and the torsion member 6. The locking hole 711 is conical in shape, and the diameter of the locking hole 711 gradually increases from the extending end of the torsion member 6 towards the other end of the torsion member 6. The side wall of the torsion member 6 opposite to the locking hole 711 is conical in shape and is adapted to the side wall of the locking hole 711.

[0051] When the user locks the torsion member 6, the tension member 72 is used to pull the torsion member 6. The conical side wall of the torsion member 6 fits with the conical side wall of the locking hole 711. As the tension member 72 gradually pulls the torsion member 6, the side wall of the torsion member 6 gradually abuts against the side wall of the locking hole 711, and the frictional force between the torsion member 6 and the locking plate 71 gradually increases, thereby hindering the rotation of the torsion member 6. Since the locking hole 711 and the torsion member 6 are in contact through a conical surface, the friction surface is large, making the locking of the torsion member 6 relatively reliable. In addition to the above, since the locking hole 711 and the torsion member 6 are in contact through a conical surface, and the conical surface is a revolving curved surface, the torsion member 6 can be locked at any position of rotation, and stepless adjustment of the torsional restoring force of the torsion spring 5 can be achieved. Compared with the traditional use of a ratchet mechanism to lock the rotational position, the locking method by friction force in this solution can not only achieve stable locking, but also has a simpler structure than the ratchet structure and is more reliable, which is beneficial to cost savings.

[0052] Referring to Figure 3 , the tension member 72 includes a rotating ring 721. The rotating ring 721 is threadedly connected to the extending end of the torsion member 6, and the rotating ring 721 and the locking plate 71 are detachably abutted. When the user uses the tension member 72 to pull the torsion member 6, the rotating ring 721 is rotated. The rotating ring 721 first abuts against the locking plate 71, and then as the rotating ring 721 continues to rotate, under the action of the thread, the extending end of the torsion member 6 continues to extend outwards from the rotating ring 721, and the abutting force between the torsion member 6 and the locking plate 71 gradually increases until the rotating ring 721 cannot continue to rotate, and the torsion member 6 is locked. Since the thread has a self-locking function, the relative rotation between the rotating ring 721 and the torsion member 6 can be stably locked, and the torsion member 6 can be stably locked.

[0053] For the locking component 7, in addition to the above embodiments, in other embodiments, the locking component 7 may further include a locking plate 71 and a rotating ring 721. The locking plate 71 is fixed to the first fixed seat 1. Through holes are provided at the positions of the locking plate 71 and the tensioning member 72 opposite to each other. One end of the torsion member 6 extends out of the locking plate 71 through the through hole, and the rotating ring 721 is threadedly connected to the extended end of the torsion member 6. A baffle is fixed to the other end of the torsion member 6, and the diameter of the baffle is greater than the diameter of the through hole. When the user turns the rotating ring 721 to tension the torsion member 6, the baffle abuts against the locking plate 71. As the rotating ring 721 is continuously tightened, the friction force between the baffle and the locking plate 71 continuously increases, and finally the relative rotation between the torsion member 6 and the locking plate 71 is prevented, thereby realizing the locking of the torsion member 6.

[0054] Referring to Figure 5 , the torsion member 6 is provided with an anti-rotation hole 61, and the end of the torsion spring 5 extends into the anti-rotation hole 61, thereby realizing the connection between the end of the torsion spring 5 and the torsion member 6. Specifically, the anti-rotation hole 61 can be a polygonal hole, an elliptical hole or other irregularly shaped holes. For example, the shape of the anti-rotation hole 61 can be a triangle, a quadrilateral, a pentagon, a hexagon, an ellipse or other shapes. As Figure 5 shown, in the embodiment of the present application, the anti-rotation hole 61 is preferably a hexagonal hole, and one end of the torsion spring 5 close to the torsion member 6 is set to be hexagonal. The torsion member 6 is slidably sleeved on the end of the torsion spring 5 through the anti-rotation hole 61. The torsion member 6 and the torsion spring 5 cannot rotate relative to each other, but can slide along the axis direction of the torsion spring 5.

[0055] When the torsion member 6 and the torsion spring 5 are assembled together, only by inserting the end of the torsion spring 5 into the anti-rotation hole 61 can the sliding connection between the torsion member 6 and the torsion spring 5 be realized, and the relative rotation between the torsion member 6 and the torsion spring 5 can be prevented, making the assembly between the torsion member 6 and the torsion spring 5 more convenient and fast.

[0056] Continuing to refer to Figure 5 , one end of the torsion spring 5 far from the torsion member 6 is connected to the rotating cylinder 3. A connecting plate 31 is fixed on the rotating cylinder 3. A connecting hole 311 is provided at the position of the connecting plate 31 opposite to the torsion spring 5. The connecting hole 311 is hexagonal, and the position of the end of the torsion spring 5 cooperating with the connecting hole 311 is also set to be hexagonal. When the torsion spring 5 is inserted into the connecting plate 31 through the connecting hole 311, the rotating cylinder 3 and the torsion spring 5 cannot rotate relative to each other. In order to prevent axial play between the two, after the torsion spring 5 extends out of the connecting plate 31 through the connecting hole 311, a nut 51 is threadedly connected to the end of the torsion spring 5.

[0057] Referring to Figure 1The protruding end of the torsion member 6 is fixed with a torsion handle 62, which is used to twist the torsion member 6; the rotating ring 721 is fixedly connected with a toggle handle 722, which is used to toggle the rotating ring 721 for rotation. When the user needs to twist the torsion member 6, first loosen the rotating ring 721 by toggle handle 722, and then rotate the torsion member 6 by the handle to adjust the strength of the torsion spring 5. After the adjustment is completed, the rotating ring 721 is toggled in the opposite direction by toggle handle 722 to achieve the locking of the torsion member 6. Through the cooperation of toggle handle 722 and the handle, it is convenient for the user to adjust the strength of the torsion spring 5.

[0058] Reference Figure 2 The first fixing seat 1 is hollow, and the locking plate 71 is fixed to the open end of the first fixing seat 1. The cooperating part of the torsion member 6 and the torsion spring 5 can be hidden in the first fixing seat 1, which is beneficial to the beauty and uniformity of the appearance. Moreover, the entire circumference of the locking plate 71 is supported by the first fixing seat 1, the connection between the locking plate 71 and the first fixing seat 1 is relatively stable, and the end of the torsion spring 5 can be connected relatively stably, so that the partition cloth 4 can be pulled out and retracted relatively stably.

[0059] Reference Figure 1 , 2 5. A mounting plate 11 is provided at one end of the first fixed seat 1 away from the torsion member 6. An end mounting member 32 is fixed to the end of the rotating drum 3. The end mounting member 32 is embedded in the mounting plate 11 and is rotatably connected to the mounting plate 11. The mounting plate 11 is connected to a rotation locking member 8, which is used to lock the rotation of the end mounting member 32.

[0060] When the partition cloth 4 is pulled out to separate the space, the locking member can lock the rotating drum 3 to prevent the partition cloth 4 from being pulled further, thereby ensuring that the partition cloth 4 can effectively separate the space. Moreover, the torsion member 6 and the locking member are respectively arranged at both ends of the first fixing seat 1, and the operation distance of the torsion member 6 and the locking member is close, but they do not interfere with each other, which is convenient for the user to adjust the strength of the torsion spring 5 and also convenient for the user to lock the rotating drum 3.

[0061] Reference Figures 1-4 The mounting plate 11 is provided with an axial hole 111 and a receiving hole 112 which are connected to each other. The axial hole 111 and the receiving hole 112 are along the axial direction of the torsion spring 5. The end mounting member 32 includes a sleeve 321 and an end plate 322 which are fixed to each other. The diameter of the end plate 322 is larger than the diameter of the sleeve 321. The sleeve 321 is sleeved on the rotating drum 3. The sleeve 321 is located in the axial hole 111. The end plate 322 is located in the receiving hole 112. The locking member locks the rotation of the end plate 322. The small clearance between the sleeve 321 and the axial hole 111 is used to ensure the stability of the rotation between the sleeve 321 and the first fixing seat 1.

[0062] The cooperation between the shaft hole 111 and the sleeve 321 can realize the rotational cooperation between the rotating drum 3 and the first fixed seat 1, and the locking of the end plate 322 by the locking member can realize the locking of the sleeve 321 rotation, thereby locking the rotating drum 3, and realizing bidirectional locking of the rotating drum 3.

[0063] Reference Figures 3-6 The rotation locking member 8 includes a clamping ring 81, which extends into the receiving hole 112 and is threadedly connected to the mounting plate 11 to clamp the end plate 322. By rotating the clamping ring 81, the clamping ring 81 gradually clamps the end plate 322. After the end plate 322 is clamped, the locking of the end plate 322 is achieved, that is, the locking of the drum 3 is achieved. Under the effect of the self-locking of the thread, the drum 3 can be reliably locked.

[0064] In order to make the rotation of the clamping ring 81 more convenient, refer to Figures 3-6 A toggle plate 811 is fixedly connected to the side of the clamping ring 81 away from the end plate 322, and a plurality of toggle bars 812 are integrally formed on the toggle plate 811. When the user needs to lock the rotation of the drum 3, the clamping ring 81 is rotated by the toggle bars 812, so that the user can lock the drum 3 conveniently.

[0065] The implementation principle of a telescopic gate in the embodiment of the present application is as follows: when the user needs to use the telescopic gate, the first fixing seat 1 and the second fixing seat 2 are fixed at the position where they need to be used, and then the free end of the partition cloth 4 is pulled to the desired position, and the free end of the partition cloth 4 is fixed, and the partition is completed. At this time, the user feels whether the partition cloth 4 has reached the tightened state. If the partition cloth 4 has not reached the tightened state, the user first loosens the locking assembly 7 so that the torsion member 6 can twist the torsion spring 5, and then twists the torsion spring 5 in the direction of tightening the torsion spring 5, that is, twists the spring in the direction of increasing the rotational restoring force of the torsion spring 5, so that the rotational restoring force of the torsion spring 5 is increased, and the partition cloth 4 is tightened, so that the partition cloth 4 can be tightened even when the pulling distance is small.
